EMBROIDERY-TRIMMING APPARATUS.

Specification of Letters Patent.

Patented July "Z, 1914.

Application filed September 3, 1913. Serial N 0. 787,827.

To all whom it may concern:

Be it known that I, FREDERICK PRIon, a

citizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Embroidery-Trimming Apparatus, of which thefollowing is a specification. My invention relates to improvements inembroidery trimming apparatus, an ob ect of the invention being toprovide an im proved reciprocating cutter movable through a guide, whichlatter prevents the cutter from cutting too close to the embroidery, andalso prevents the movement of the embroidery too far under the guide,hence insuring a uniform cutting of the embroidery, and a smooth ratherthan a ragged edge.

A. further object is to provide an improved apparatus of this characterwhich will rapidly and accurately cut the edge of the embroidery, and.which is capable of adjustment for various operations.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a view in side elevationillustrating my improved apparatus. Fig. 2 is a View in vertical sectionon an enlarged scale illustrating the cutting means per se. Fig. 3 is aview in section on the line 3-3 of Fig. 2. Fig. 1 is a plan view of anordinary piece of embroidery. Fig. 5 is a face view of the cam 7. Fig. 6is a perspective view of the guide 18. Fig. 7 is a perspective View ofthe guide supporting bracket 12, and Fig. 8 is a perspective view of thecutter *bar'19.

1 represents a base plate having a frame 2 thereon, the latter providinga vertical cylindrical guide sleeve3 at its free end supporting areciprocating plunger 4. This plunger 4 is provided with a pin 5projecting through a slot 6 in the guide sleeve 3, and into a groove 6in a cam 7. The cam 7 is secured upon a shaft 8 which may be driven inany approved manner and it will be noted that the cam is provided with aplurality of cam surfaces so that at each revolution thereof, theplungers will be reciprocated a number of times. A cutter 9 is securedin socket 10 in the lower end of plunger 3 by means of a set screw 11.This cutter 9 is triangular in cross section and has a beveled lowercutting end.

12 represents a bracket which has a slot 13 therein for the reception ofa screw lt to adjustably secure the bracket to the guide sleeve,permitting a vertical adjustment of i said bracket. The lower end of thebracket 12 projects at right angles to the guide sleeve, and is providedwith a socket 15 into which the shank 16 of my improved guide 18projects. The guide 18 is secured by means of a set screw 17, and may beadjusted horizontally to exactly position the guide under the cutter. Byreference particularly to Fig. 6, it will be noted that this guide is ofgeneral triangular form, and corresponds in shape to the shape of thecutter in cross section.

On the base plate 1, acutter bar 19 is adjustably secured by means ofscrews 20, said screws being positioned in any of a plurality ofthreaded openings 21 in the base plate so as to position the cutter barwith any of its V-shaped notches 22 in register with the cutter. The bar19 may have any number of these V-shaped grooves, so that as such edgesbecome dull, the cut ter bar may be shifted to present other edges forcooperation with the cutter. As the cutter passes against the wall oredge of the notch 22, it exerts a shear cut so that the goods 23 may bereadily cut. The guide 18 is located in a horizontal plane above thecutter bar just sufiicient to permit the goods 23 to pass under theguide, but not sufficient to allow the embroidery 24 to pass under theguide. In other words, this guide 18 prevents any possibility of thegoods being moved to a position to be cut by the cutter, and thethickness of the walls of this guide controls the cutting, so that it isimpossible for the cutter to sever the embroidery or to injure the same.To facilitate this protection of the embroidery, the guide 18 at itslower edge is projected downwardly forming a V-shaped bearing 25 whichrests directly upon the goods as shown clearly in Fig. 2.

To prevent possibility of the cutter injuring the fingers of theoperator, a guard 26 is secured to the guide sleeve by means of a screw27. An opening 28 is provided in the base plate 1 below the cutter, sothat the goods which are cut may fall therethrough, and furthermore,this opening prevents any possibility of the cutter engaging the baseeven though it is adjusted to its lowest po- I the surface of cutter bar19 and moves the goods backwar'dly and forwardly toward and away fromthe guide 18. The guide allows the goods to be manipulated so that thecutter will cut into the angles of the embroidery, yet prevent anypossibility of cutting the embroidery.

Various slight changes might be made in the general form and arrangementof' parts described without departingfrom my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appendedclaims.

, Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An embroidery trimming apparatus comprising. a support for goods tobe out having a notch in one edge, a guide positioned above the supporta distance approximately the thickness of the goods to be cut, and adistance appreciably less than the combined thickness of the goods andthe embroidery, said guide having at its free end a I downwardlyextending V-shaped bearing adapted to rest directly upon the goods, anda cutter adapted to move through the guide and cut the goods against thewall of the comprising a support for goods to be cut l'having a notch inone edge, a guide positioned above the support a distance approxi-'notch, substantially as described.

'2. An embroidery trimming apparatuscomprising a support for goods to becut having a notch in one edge, a guide positioned above the support adistance approximately the thickness of the goods to be cut,

and a distance appreciably less than the combined thickness of the goodsand the embroidery, said guide having at its free end a downwardlyextending V-shaped bearing adapted to rest directly upon the goods, anda cutter conforming in shape to in shape to the shape of the notch, saidoutter movable through the guide and adapted to cut the goods againstthe wall of the notch, substantially as described.

3. An embroidery trimming apparatus comprising a support for goods to becut having a V-shaped notch in one edge, a

triangular guide positioned above the support a distance approximatelythe thickness of the goods to be cut, and of a distance extendingV-shaped bearing adapted to rest directly-u-pon-the goods, and atriangular cutter adapted to reciprocate through the guide and cut thegoods against the wall of the notch, substantially as described.

.4. An embroidery trimming apparatus, comprising a base plate having anopening therein, a supporting frame, a cylindrical guide on thesupporting frame, a reciprocating plunger in the guide, a cutter in thelower end of the plunger in line with, the opening in the base plate, acutter bar adjustable on the base plateand having a plurality of notchesin its edge, said plate adapted to'be'moved to position any ofv saidnotches in line with the cutter, a guide through which the cutterreciprocates, said guide positioned between the cutter and the cutterblade and adapted to rest at its lower edge upon the goods to be cut andengage the embroidery, means for reciprocating the plunger, and a guardon the guide located in front of the cutter,- substantially asdescribed.

5. An embroidery trimming apparatus mately the thickness of the goods tobecut, and a distance appreciably less than the cutter of the same shapein' cross section, said cutter adapted to cut the goods against @thevnotched edge of the support, substanitially as described. the shape ofthe guide and also conforming 1 In testimony whereof I have signed myFREDERICK PRICE.
